I did and it was glorious. you booted up your Genesis and got a menu with 50 games to choose from in different categories, all over cable, for like $15 a month. Check out these videos:

big hour long thing showing off some demo roms that were dumped:

One really stormy night my sister and I were playing Tiny Toon Adventures ACME All-Stars and in the middle of the bowling minigame we experienced a power surge that apparently made our Genesis unable to utilize the Sega Channel accessory, but still able to play regular cartridge games somehow? Not sure how that all worked but that's what the technician said and it really sucked.

tiny picture but this is what it looked like when I had it:

anyways this has been on my mind a lot recently for some reason and just wanted to share.

all i really knew about the Sega Channel was that it was the only way you could get Mega Man: The Wily Wars in North America

things like that and the Satellaview are super interesting to me since i had no idea they existed until long after they were defunct. they seemed really ahead of their time, though i imagine the market of people who could actually take advantage of them was pretty niche.

it apparently only had 250,000 subscribers in the US at its peak. its biggest problem was that it started in 1994, fairly late into the system's life cycle so it didn't have a lot of time to really pick up steam. but I didn't get a next gen console until Christmas 1997 with the N64 so hell I didn't care, Sega Channel seemed like magic to me.

I didn't have it and am not sure I even heard of it back then, but it was decades before its time. I wasn't interested enough in Sega to have gotten it, though in hindsight they did have plenty of content, but I was much more into SNES. Especially at that point in time. Genesis was on its last legs and 12th add-on by then, and Saturn was right around the corner, which would have worked fine, if the Saturn didn't fail so miserably. I did actually buy Saturn at launch, one of the last consoles I would so that for, an awful launch followed closely by immediately being overtaken by Sony.

I'd be really interested in a long-form write-up of Sega Channel, because what Shane said is exactly true: this thing was wildly far ahead of its time. But a lot of people may not have even known it existed. This merits some exploring.
